It's Tow motor and super old I can't post pics on here but thanks I'll have a look I thought I checked atound the area your talking about. Will inspect again it's a 60's looking Fork with Towmotor stamped on the top of the back counterweight

Is it a Towmotor or is that your nickname for a fork lift truck. If it is a Towmotor then the serial # is stamped on the frame right under where the tilt cylinder rods protrude through the frame. I think it is under the LH one but check both. The number should start with a 3, 4, 5, 6 or 7. If it's super old then it might start with an LT.
